Some programming features provided by the Positip 880,
such as Arcs, Blends and Chamfers, are not easily
machined on a manually operated machine. These tool
paths require two axes with simultaneously controlled
motion. The Positip 880’s Contour View function provides
a graphical method for the operator to approximate these
tool paths. See "Contour View" on page 81for details
regarding this function.
